86 - Atomic Number ( Number of Protons )
RN (Radon)
222 - Mass Number
atomic number 86 - a radioactive gaseous element formed by the disintegration of radium; the heaviest of the inert gasses; occurs naturally (especially in areas over granite) and is considered a hazard to health.
Rn, Radon, atom no. 86, period VI, group 18, noble gas, (just below Xenon in the Periodic Table)
Radon is a none metal element. atomic number of it is 86.
Element 86 is radon (Rn).
The element is Radon (Rn).
Element 79 on the periodic table is gold.
This element is radon.
Radon
It is gold.
Fluorine has a stronger attraction to electrons than any other element, so when it bonds to another element that element is going to either donate electrons to the fluorine, or share electrons with fluorine getting the disproportionate share.
The element is helium, with symbol He.
Its valency is 3 i.e. 8-5.The element is a non metal since it has 5 electrons in the outermost shell.Hence, it is very difficult for the element to loose 5 electrons and would be easier togain 3 electrons .Hence, the element gains 3 electrons and thus we consider its valencyto be 8- no. of valence electrons.
The 19th element is potassium, which has the atomic symbol K. It has 19 electrons, including one valence electron that can be easily lost.
The element that has a mass number of and two valence electrons is an isotope of calcium.
Rn has 86 electrons, Th is the closest to having an atomic mass of 230
Pb+4, Lead
Radon. Because it has 86 protons, it has 86 electrons, so therefore, the atomic number is 86 on the periodic table.
Radon is a non metal element. There are 86 electrons in a single atom.
Helium has 2 electrons and Radon has 86 electrons but both have 8 valence electrons (8 electrons in their outermost shells)
This is radon, it has a full outer shell of electrons, so it is technically non reactive
it would be an isotope of Radon, (Radon-230)
Radon has 86 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the Rn isotope - 86
The element with 86 electrons, 125 neutrons, and 82 protons is the element Lead (Pb). The number of protons (atomic number) determines the element, and in this case, it is 82 for lead. The sum of protons and neutrons gives the atomic mass, which is 207 in this case, making it the isotope with mass number 207.
The number of electrons in a radium atom is usually 88. If it goes though bonding however, it will tend to lose those two outer electrons, and become a radium ion. If it bonds with oxygen, which has 6 outer electrons, it will lose the two outer electrons it has to become a radium ion with a full outer level of 86 electrons, and oxygen will get a complete outer level of 8 electrons. Radium will become Ra2+, a typical radium ion, also known as Radium 86, as it loses 2 electrons.
leadLead but it has 82 protons and electrons and 125 neutronshope i helpedLead 125, with a -4 chargeradon
